How Hosiqo compares and tests toolsFinal recommendation
Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and StreamText when real-time captioning and translation in classrooms and lectures for accessibility matters most. Try them side by side on real calls before deciding — needs vary by team.

Aiko is a native transcription app for macOS, iOS, and visionOS, developed by Sindre Sorhus, that converts speech to text from meetings, lectures, and recordings entirely on-device. It uses OpenAI's Whisper model running locally, so audio never leaves the user's device, which makes it appealing for students and professionals with privacy requirements. Aiko transcribes both audio and video files in common formats such as .m4a, .wav, .mp3, .mp4, and .mov, and supports around 100 languages. Transcriptions can be exported in multiple formats, including JSON, CSV, and SRT subtitles, and the app includes a word-replacement feature to automatically correct recurring errors. It also integrates with Apple Shortcuts for automation workflows. Because Aiko prioritizes accuracy over speed, it does not perform live transcription while recording and currently does not include speaker detection, so it is best for transcribing recorded lectures, interviews, and meetings after the fact. The app is offered as a Universal Purchase with a free trial via TestFlight, making it a low-cost, privacy-first option for turning lecture and meeting recordings into searchable text. Pricing varies by plan. Check the official website for current pricing.

StreamText is an enterprise real-time captioning platform, founded in 2003, that delivers spoken words as live captions to web pages, devices, and conferencing tools. It supports two modes: professional human captioners (using stenography, re-speaking, and text interpreting) and AI-powered automatic speech recognition (ASR), which converts speech to text in real time and produces captions, translations, and transcripts. Source audio is captioned live and streamed to an ADA-compliant viewer that works with screen readers, while AI captioning recognizes around 20 source languages and offers realtime translation into well over 100 languages. Captioned sessions can be exported as timed-text transcript files such as .srt and .vtt, and StreamCast lets organizers overlay captions onto videos and presentations. It integrates with Zoom, Webex, YouTube, and Adobe, and exposes a full API for OEM and third-party embedding. It is aimed at corporate and hybrid events, conferences, classrooms, trade shows, and legal or government settings needing accessibility. Pricing is usage-based per minute with no subscriptions or setup fees.
